AR-PRO 11x4.00-5|11x4.50-5|11x6.00-5 Heavy Duty Replacement Inner Tube with TR-87 Bent Valve Stem (2-Pack) - for Wheelbarrows, Mowers, Hand Trucks and More

What It Is

This is a heavy-duty replacement inner tube (2-pack) designed for 11-inch tires with 4.00, 4.50, or 6.00 width profiles. It’s for lawn mowers, wheelbarrows, hand trucks, and small utility trailers that use tubed tires.

Fitment & Compatibility

Before buying, check your tire’s sidewall for its size stamp (e.g., 11x4.00-5, 11x4.50-5, or 11x6.00-5). This tube fits all three widths but only on 5-inch rims (the “-5” in the size). It will not fit tires with different rim diameters (e.g., 4-inch or 6-inch rims). Measure your existing tube’s valve stem – this has a TR-87 bent stem (approx. 1.5-inch long, 90° bend), common on mowers and wheelbarrows. If your machine uses a straight or shorter stem, you may need an adapter or a different tube. No specific brand or model restrictions – it’s a universal aftermarket part.

Key Things to Know

• Quality: Heavy-duty rubber (0.095-inch thick) resists punctures better than standard tubes, but still prone to pinch flats if underinflated.
• Installation: Moderate difficulty – you’ll need tire irons, a bead breaker, and patience. Bent stem can be tricky to seat in some rims. Watch for pinching the tube between rim and tire bead.
• Common gotcha: The TR-87 stem is metal and can corrode over time – apply anti-seize or rubber lube to the stem base before mounting.
• Two-pack value: Cost-effective if you need spares or have two identical tires. Single tubes are often similar price per unit.

Should You Buy It

Buy this if you have 11-inch tubed tires on a mower, wheelbarrow, or hand truck and need a durable, affordable replacement. It’s a solid choice for DIY repairs, but skip it if your tire uses a different rim size (e.g., 4-inch or 6-inch) or a straight valve stem (TR-13). For occasional use, the 2-pack is a smart spare to keep on hand.
